You want to be able to ‘feel’ your favourite films and not just watch and listen to them. We have included a perfectly matching subwoofer for this precise reason with the new QUBE 12. Unlimited capacity thanks to the 32 cm long-throw woofer and the rich 500 Watt sinewave amplifier power combine to ensure brute elemental force and perfect control of the deepest octaves. The gigantic magnet used for the powerful woofer provides the impressive amplifier output power with incredible precision. The QUBE 12 combines optimum stable pulse fidelity with the dynamics. The QUBE 12 not only uses Cinch connectors but also professional XLR connections to provide the interconnections with the AV receiver.

CHROMIUM Style Surround Set; STYLE 8, STYLE 1, STYLE 2, PHASE R6, QUBE 10

This actually the translation of our very good test at the lite magazin. Well proportioned, excellent, graceful – just the words we would use ourselves. lite magazine has listened to our Chromium Style series


Quadral’s Chromium series is well-proportioned, excellently made and clearly predestined for use in tastefully designed living areas, judging by its elegantly graceful form. Tasteful, refined, but also brutish and powerful when it needs to be - features also reflected in the sound performance. If you have the right AV receiver, you can easily fill rooms up to 50 square metres with the setup tested here. The description “fill” is chosen deliberately; the Quadral octet has a pair of flat loudspeakers that you can use flexibly to create more volume for Atmos use, delivering an even more impressive and more intensive home cinema experience.

"Elegant and powerful" ... these are the first words of the current HEIMKINO edition about our STYLE & PHASE surround set

At the same time 8 loudspeakers went to HEIMKINO last month to face the critical eyes and ears of the test editorial. The "travel group" consisted of the new speakers PHASE A10, CHROMIUM STYLE models 1, 2 and 8 as well as powerful subwoofer QUBE 12. With a "soundtip" and grade 1+ in the luggage, the set took off for the journey home; and this to the great joy of those who stayed home. The conclusion of the testers: "With the slim, excellently processed chromium set, quadral has succeeded a big pitch. The 5.1.2 home cinema set that we have tested delivers first-class film sound, which is dynamic, tonal and convincing in terms of spatiality throughout the line. The Qube 12 is an extremely powerful subwoofer in our set for captivating and dry bass reproduction, two Dolby Atmos PHASE A10 units deliver the third dimension of the film sound from above. quadral Chromium Style: a real recommendation for demanding home cinema and hi-fi lovers!

Sound from all sides!

Large multi-channel test at AREA DVD: 10 quadral loudspeakers lined up to create the perfect surround sound. In detail: 2x quadral PLATINUM M40, 2x PLATINUM M20, 1x PLATINUM M10 BASE, 1x QUBE 12 and 4x the new effect-stage PHASE A10. Together, the ensemble won the title "price class reference". The bottom line of the test project: multi-channel experts from Hanover: The Quadral 5.1.4-set pleased us in the test with a far above-average performance. The spatial effect with four tower modules is gigantic; one feels enveloped by all sides and in all dimensions of sound. The quadral ensemble converts very well, what “immersive sound” wants to achieve. All components are level-resistant. The QUBE 12 active subwoofer impresses furthermore with its impressive design. The built-in output stage with a full 500 watt sine-wave power fits into the first-class overall picture of this multi-channel system. Thanks to the RiCom V tweeter, the Platinum components included in the set, play up to 50 kHz, making them ideal for high-definition audio media. The processing is excellent, even in the detail we do not find any defects. The top firing modules, phase A10, however, are technically - with a broadband chassis - very simple. Here the competition (KEF, ELAC TS3030) puts in more effort. With the 5.1.4 set of Platinum M, Phase A10 and QUBE12, quadral delivers an impressive statement for modern multi-channel sound"

Result: Price class reference (multi-channel loudspeaker sets upper class), the test of 18.11.2016 is available  here

"The low-distortion reproduction coming from the sleek Bauhaus-style Quadral Qube will enthral any listener. It was noticeably unobtrusive during the reproduction sequences yet it had a decisive emphasis when reproducing spec­tacular sound effects, such as those in the flight scenes in ‘Avatar’. Even music gourmets will come to love it as it makes the complete music spectrum audible right down to the deepest frequencies.”

+ It can perform loud and deep, and very cleanly as well
- Available only in highgloss black and highgloss white

Test verdict: Very good  76%

Price/performance ratio: Very good Testwinner (4 subwoofer tested, 2 x very good, 2 x good)


Audiovision, January 2013

PLATINUM M set, consisting of: PLATINUM M50, PLATINUM M25, PLATINUM M10 and QUBE 12

"Conclusion Quadral's Platinum-M set does not come cheap, but the set is worth its price. The superb finished high-gloss ensemble does not need take up a lot of space, but it will easily fill a huge room with superb elemental bass tones. Both music and voices always sound natural and films are reproduced homogeneously and non-stressfully. This is why the set gets 90 points (out of 100) and reaches our "reference class."
